Effect of jet mixing enhancement by pulsed blowing on infrared radiation of plume

  • A three-dimensional infrared (IR) radiation code of the plume was developed by the finite volume method (FVM) coupled with narrow band model in non-gray absorbing-emitting media. The infrared radiation of the unforced plume and the forced plume, which is mixed by injecting high amplitude and low mass flux plused slot jets into subsonic shear layer were simulated by the code. The 3-D flow field of the jet was simulated numerically by FVM, renormalization group(RNG) k-ε turbulence model. The results indicate that small injection flow rates (about 3%) can make sharp increases in both velocity and temperature decay rates at middle Mach number. At the zenithal angle of 90°, the IR radiation of the plume at each azimuth angle has tremendous reduction, and the decreases in the plane parallel with the actuators are larger than those in the plane perpendicular to the actuators.
